MY PSU is currently making a clicking noise after being on for around 3 minutes. Before that it is making some screeching noises i believe it is something to do with the PSU fan but i am unsure.

I have uploaded 2 youtube videos with the sounds that the power supply is making. Any feedback would be helpful :)

Is this a major problem or can it wait a few months for a replacement?
